How to get partner to help?

How do I get my partner to help? I sent him a tik tok that said something along the lines of “when you go check on the baby crying and find his dad ignoring him to play video games” and i was like “you the other night” (although he wasn’t playing video games, just got himself ready to bed then went to bed while i was getting our daughter ready so couldn’t get the baby at the time). So then he proceeds to say i always start shit and don’t ask me for help then and I’m just like you don’t help anyways. He then says that that motivates him to be worse instead of better and that don’t ask what time he’s coming home today (probably going to go drink with his friends) and i’m like huh??? like how can i motivate him to be better then?
